Like others said change it if you want. FYI what ever is in there is still good oil doesn't go bad in months. It takes a few years of abuse.

As far as brand goes. Go with synthetic anything.

But. Here's the truth behind that rare special order brands like Enos, Motul, and Royal Purple. Say your just a bit out of town, a quart low and all the auto parts stores are closed? Your pretty much screwed cause you can't find it anywhere.

Now if you go with Mobil 1, Castrol, Penzoil or any of those other brands guess what? They are everywhere. So just a little something to think about.
